■Barometer
■ Altimeter
■ Current fuel consumption
Displays the atmospheric pressure in the vehicle.
The displayed atmospheric pressure ranges from 17.8
IN.HG (600 hPa) up to 31.0 IN.HG (1050 hPa).
Displays the approximate altitude.
The displayed altitude ranges from -1500 ft. (-500 m)
up to 13000 ft. (4000 m).
Displays the elapsed time after the engine starts.
When the engine is started, driving time is counted
from 0:00.
Up to 19:59 (19 hours, 59 minutes) can be displayed.
■Altimeter mode
The indicated altitude of a single position may deviate according to the atmospheric
pressure and temperature.
While the altitude mode is displayed, push the “ ▲” or “ ▼” button to increase/
decrease the altitude by 50 ft. (or 10 m).
To reset the adjusted altitude, push and hold the “RESET” button for more than 1
second.
CAUTION
■Caution while driving
Do not adjust the display.
Doing so may cause the driver to mishandle the vehicle and an accident, resulting in
death or serious injury.

Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
●Rain-sensing windshield wipers (if equipped): Turn the wipers off before wash-
ing the vehicle. (→P. 1 3 8 )
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows. Before entering an automatic car wash, check that the fuel filler door is
closed.
■Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard brushes
or abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same
mild detergent and wax as used on the paint.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● If water no longer beads on clean paint, apply wax when the vehi-
cle body is cool.

Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your Lexus dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading.
●Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.
●Do not bleed or reduce tire inflation press ure after driving. It is normal for the
tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

5-2. Steps to take in an emergency
CAUTION
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [tire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure warning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).

Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
